Application filed February ll, 1920. terial lt'o. 3157,??7.

i provide in a collapsible container an improved discharge regulating means whereby a measured quantity is discharged at each operation.

Further objects; and objects" relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. I

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which;

Figure I is a plan view of a collapsible container, such as a tooth paste tube, embodying the features of my invention.

Fig. 11 is a detail view partially in central longitudinal section on a line corresponding to line 2-2 of Fig. T.

Fig. lllll is a similar detail section wit the cap removed.

' Fig. TV is a detail section on a line corresponding to line 4-4 of Fig. HT, showing structural details.

Fig. V is a top perspective view of the discharge control member.

In the drawing similar reference characters refer to similar parts throughout the several views, and, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the body of a container of well known constructioirprovided with a conical discharge end 2 terminating' in the threaded neck 3 having the discharge opening 4 therein. The container is provided with a threaded cap -5 Within the container, is a disk 6 of a diameter somewhat less than the body of the tube, as shown in H, the disk being which is freely removable.

flexible tube or collapsible adapted to seat against the conical-portion of the container, as shown in Fig. Tllll. The disk is provided with an' arm 7 which extends through the discharge opening 4 to be engaged by the cap 5, so that the disk isforced rearwardly or to its open position when the cap is threaded upon the neck, as shown in Fig. H. The arm 7 is preferably provided with the lug 8 projecting laterally to engage the neck limiting the inward movement of" the control disk.

This pre- ,vents its accidental dislocation before the tube is filled and also prevents its being pushed out of place after the tube is filled.

lln operation, the cap being in position, the disk 6 is held from its-seat so that the contents of the tube will flow around the disk into the conical portion of the tube, and when the cap is removed,the pressure of the contents of the'container on the disk will force it to its seat, forcing out a charge of the contents, but preventing continued flow thereof.

The arrangement of the arm through the discharge opening keeps this opening free, that is, it prevents the o ening from becoming clogged by the dried contents of the tube. 1 With this arrangement of parts, T

of the-tubes contents may be delivered at each operation.

The structure'is very simple and economical to produce, and is not likely to become ino erative or get out of repair in use.

aving thus described my invention, what T claim as new and desire to secure by Letters Patent is:

1; The combination of a collapsiblecontainer having a conical portion at its discharge end and a threaded neck with a discharge opening in the end'thereof, a cap threaded to remo'vably engage said neck, and a disk disposed within said container and adapted to seat on the conical portion thereof, said disk having an arm loosely disposed through said discharge opening to be engaged by said cap and unseated thereby, said arm being provided with a lug at its outer end engaging said neck to limit the inward movement of the disk.

2. The combination of a collapsible container having a conical portion at its discharge end and a threaded neck with a discharge opening in the end thereof, a cap threaded to removably engage said neck,

llltl and a disk disposed within said container and adapted to seat on the conical portion thereof, said disk having an arm loosely disposed through said discharge opening to be engaged by said cap and unseated thereby.

3. The combination of a collapsible container having a threaded discharge neck at one end, a removable cap threaded upon said neck, and a discharge control disk disposed within said container for bodily movement longitudinally thereof, said disk' constituting a cut-ofi when in one position and being provided with an arm disposed through the discharge to be engaged by the cap, whereby when the cap is closed the disk is forced to its open position to permit the passage of the containers contents and is carried to its closed position by pressure of the contents of the container thereon when the cap is removed.

4. The combination of a collapsible container having a threaded discharge neck at one end, a removable cap threaded upon said neck, and a discharge control disk disposed within said container for bodily movement longitudinally thereof, said disk constituting a cut-off when in one position and being prox'ided with an arm disposed to be engaged by the cap, whereby when the cap is closed the disk is forced to its open position to permit the passage of the containers contents and is carried to its closed position by pressure of the contents of the container thereon when In witness whereof, my hand and seal in I have hereunto set the presence of two witnesses.
